why people are asking questions now. if osama bin laden's courier had their numbers in his cell phone, clearly those ties still existed and does that mean, therefore, that pakistan's intelligence services knew about where bin laden was. the evidence doesn't point to that yet, but it certainly opens up that avenue for people to look at. >> you tend to wonder if, indeed, that's true, what kind of impact that is going to make on the relations between the u.s. and pakistan and also, you know, bottom line, nic, getting this information, learning about what type of phone numbers were there, the possible connections. could this stop future attacks? >> reporter: it certainly will put a number of people on notice, particularly in mujahadin aanyone that has been dealing with them, that they are potentially going to be looked at as suspects in this sort of broader investigation into who knew what about where bin laden was hiding.
